SWIVEL FOR PIPES.

Application filed .Tune 4,

To all whom t may concern:

Be it known that I, BENJAMIN F. Perron,

a citizen of the United .Sta-tes, residing at Valentine, in the countyof Cherry and State of Nebraska, have invented certain new and usefulImprovements in Swivels for Pipes; and I do hereby declare the iollowingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference be'- ing had to the accompanying drawings, andto the letters and figures ot reference marked thereon, which form apart oi` this specification.

The object 01' this invention is to provide a swivel for the adjoiningends of two pipes, sai-d swivel cooperating with one of said pipes sothat the said pipe is swiveled in the coupling.

The invention is clearly shown in the accompanying drawing, in which:

Figure l is a view in side elevation oi' two pipes equipped with myswivel, and

1igure 2 is a view in central longitudinal section thereof.

Referring now in detail to the drawings:

l and 2 designate two pipe sections, thc latter being provided with anannular head 2', or integral enlargemenn and with an integral collar 2aof lesser diameter than the head 2 and adjoining the same.

As shown, a sleeve 3 encircles the pipe 2 and is provided toward bothends witherteriorly threaded portions 1i, Ll adapted to be threaded ontocoupling members 6 and 6. The pipe l is threaded into the couplingmember G, while the pipe 2 projects loosely into the coupling member 6.vWhen the sleeve 3 is screwed into the threaded coupling 6 it bearsagainst the head 2, thus holding the pipe 2 against longitudinalmovement, but permitting swiveling or rotary Specification of LettersPatent.

movement ot' the ber 6.

Encircling a portion of the pipe 2, and within the sleeve 3, is apacking ll, bearing, at one end, against the collar 2a.

A cylindrical packing compression member l2 encircles the pipe 2 andprojects into said sleeve 3, and bears, at one end, against the adjacentend of the packing l1. Then the. coupling member 6 is screwed on theadjacent threaded end d of the sleeve 3 the end of the member 6 contactswith the cylinder l2 and moves the same toward the packing l1, thuscompressing the same.

I have, in the appended claims, referred to the members 6 and G by theexpressions first coupling member7 and second coupling memberrespectively.

This swivel is to be of use on pipes for air, water, steam, gas, oil, orany place a swivel is needed in pipes.

What I claim to be new is:

The combination of two pipes, two coupling members, one of said pipesbeing threaded with the iirst coupling', and the other pipe passingloosely through the second coupling member and being provided with a.lateral head swiveled in sai-d first coupling' member, and a` sleeveencircling` said headed pipe, said coupling members being threaded onthe respective ends of said sleeve, and said sleeve bearing laterallyagainst said head, to prevent longitudinal movement of said headed pipe,a packing in said sleeve and encircling said headed pipe, and a.cylindrical member projecting at oneI end into said sleeve, and at itsother end into said second coupling member and encircling said headedpipe, and bearing, at one end, against one end of said packing.

In testimony whereof I hereunto aiiiX my signature.

pipe in said coupling mem- BENJAMIN F. PAXTON.
